I '0 all whom it may concern. 7

Be it known that I, JUAN An'ronio O'rnno, citizen of the Argentine Republic, and resident of La Plata, Argentina, have invented certain new and useful lm 'n'o\'ements in an Electric interrupter, of which the following is a specification.

This invention relates to an interrupter which is described in the specification filed under date of December 26th 1917 under Number 208,877, being a divisional application thereunder,

To facilitate the explanation of the invention, a sample apparatus embodying it is illustrated in the accompanying drawing, i which:

Fig. 1 is a View of the interrupter;

Fig. 2 is a detail in enlarged scale of a part of the interrupter, showing in dotted lines the different positions of some of the parts.

In the drawings, like parts are indicated by similar characters in all the figures.

The apparatus embodying the interrupter consists of four principal parts: the interrupter proper, the transformer, the condenser and a resistance, the construction being as follows:

[Me ramp tier.

The interrupter (Fig. 1) is formed by a core A, of small soft iron wires, with a total dian'leter of 17 millimeters by nine centimeters in length. On this core there is wound a coil P of covered copper wire having a diameter of approximately to of a millimeter.

In front of the said core A and held by a steel spring D, is located an armature piece E of soft iron, in such a way that it may be attracted by the energizing of the core A.

In the central part of this armature piece E and opposite to the core A, a cylindrical contact A of German silver or nickel having a diameter of from 5 to 6 millimeters, is either screwed or riveted.

In front of this contact piece A there is a similar contact 1. of the same metal and similar diameter, attached to a brass adjust ing screw F which in its turn is held by a standard G, also of brass.

At the end opposite to the contact the said screw has a fibre or ebonite disk H by means of which it may be turned witnout rocking movement; all of these lllOVGll'lQllilS serving to change constantly the points of contactthrough which the current passes. l urthermore, by this device the two points of contact are formed at different levels or planes.

As best shown in Fig. 2, the nickel cylinders A and A are not in the same plane, A being slightly higher than A, so that the points of contact with the inclined disk X (also nickel) are made at a different level. lhe current, in passing through the interrupter, is attracted by the energizing of the core A and the iron piece E, thus changing the position of the inclined disk X and producing two spark breaks or interruptions, one a the lower port of the cylinder or contact A and upper face of disk X, and the other at the upper part of the cylinder A and lower face of disk X. At the same time these two points of contact constantly change position on account of the movement imparted to the disk X, as indicated by the dotted lines in 2.

The principal feature of the interrupter of my invention lies in the fact that the con tacts A and A are not on the same level as in the usual types, this difference of level havin been found indispensable for the highest eiiiciency. lhis feature together with the resiliently suspended disk between the two contacts constitute a complete novelty over all known forms of interrupter and produce the technical effects described here inbefore.

It has been found in practice that this arrangement of devices gives a very high efficiency and regularity in the production of high frequency currents, and this interrupter with the inclined disk X as above described is fundamental in this apparatus since with it there army he ehtained with the greatest regularity :1 current of Very high rrequeney.

The diameter of the Wire in the eeii carried by the core A, as also the size er the latter, may he varied according to the size a; at capacity of the apparatus to he eenstrueted.

Having thus described my invention What I claim and desire to protect by Letters Patent at the United States of America is:
